<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>Class for plot graphs of block's cpustat properties. </p>
<p>This class lets us plot graphs for QVStat block's output properties. Each <a class="el" href="classQVProcessingBlock.html">QVProcessingBlock</a> object is created with a property containing a stat object, resuming its time consumption and internal statistics. The class <a class="el" href="classQVCPUPlot.html">QVCPUPlot</a> can be used to plot those time statistics.</p>
<p>The following code features how to create a CPU plot object in a QVision application:</p>
<div class="fragment"><pre class="fragment"><span class="keywordtype">void</span> main()
        {
        [...]
        ComponentTreeBlock componentTreeBlock(<span class="stringliteral">&quot;Component Tree&quot;</span>);
        CannyBlock cannyBlock(<span class="stringliteral">&quot;Canny operator&quot;</span>);
        ContourPainter contourPainter(<span class="stringliteral">&quot;Contour painter&quot;</span>);
        [...]
        <a class="code" href="classQVCPUPlot.html" title="Class for plot graphs of block&amp;#39;s cpustat properties.">QVCPUPlot</a> cpuPlot(<span class="stringliteral">&quot;CPU Plot&quot;</span>, <span class="keyword">true</span>, 10);
        componentTreeBlock.linkProperty(<span class="stringliteral">&quot;cpu stats&quot;</span>, cpuPlot);
        cannyBlock.linkProperty(<span class="stringliteral">&quot;cpu stats&quot;</span>, cpuPlot);
        contourPainter.linkProperty(<span class="stringliteral">&quot;cpu stats&quot;</span>, cpuPlot);
        [...]
        }
</pre></div><p>This application will display a plot like the following:</p>
<div align="center">
<img src="qvision_cpuplot_window.png" alt="qvision_cpuplot_window.png"/>
</div>
<p>By default, the <a class="el" href="classQVDefaultGUI.html">QVDefaultGUI</a> includes the following button for CPU plot statistics displaying, which opens a <a class="el" href="classQVNumericPlot.html">QVNumericPlot</a> widget plotting the block CPU usage:</p>
<div align="center">
<img src="qvision_gui_graphbutton.png" alt="qvision_gui_graphbutton.png"/>
</div>
<dl class="see"><dt><b>See also:</b></dt><dd><a class="el" href="classQVNumericPlot.html" title="Class for plot graphs of block&#39;s int or double properties.">QVNumericPlot</a> </dd>
<dd>
<a class="el" href="classQVHistogramPlot.html" title="Widget for plotting QList&lt;double&gt; property values from a block, as an histogram...">QVHistogramPlot</a> </dd></dl>
